This project has students perform nondestructive laboratory work on truss assemblies and members of varying geometry to verify loads and deflections that were predicted by classroom problem solving. Implementation includes the construction of pin-connected truss models and machine components with varying geometry. These are instrumented with strain gages and appropriate readout equipment in order to demonstrate load sharing and distribution in trusses and the phenomena of stress concentration factors. The project permits the student to manipulate physical models in the laboratory to demonstrate topics that now rely solely on problem solving.

这个项目让学生对桁架组件和不同几何形状的构件进行无损实验室工作，以验证课堂问题解决所预测的载荷和挠度。 实现包括构建销连接桁架模型和具有不同几何形状的机器部件。 这些都装有应变计和适当的读出设备，以证明在桁架和应力集中系数的现象的负荷分配和分布。 该项目允许学生在实验室中操纵物理模型，以演示现在仅依赖于解决问题的主题。
